Patent GB-1048845-A (GB)
Title: Improvements in manufacture of foam products
Inventor: WILLY JOHN
IPC: B29C44/32
Filed: 1964-02-06
Abstract: <PICT:1048845/C3/1> A method of making foam products comprises forming a liquid foaming mixture, spreading the mixture over a carrier surface, disposing a covering surface over said mixture and allowing substantially complete gas generation and expansion of the mixture to form a substantially self-supporting foamed sheet, chilling said sheet immediately after said expansion while it is tacky, thereby solidifying the sheet so that it loses its tackiness with respect to the adjoining carrier and covering surfaces, and stripping at least one of said surfaces from said sheet.  In an example, a pre-mixed resin comprising two component polyether-based prepolymer systems, e.g. a pre-polymer of toluene diisocyanate and an organic compound having two or more diisocyanate reactive groups with an excess of toluene diisocyanate is mixed with silicone oil and placed in a reservoir 11.  A catalyst mixture comprising N,N,N,N - tetramethyl butane diamine, triethylenediamine, and water is placed in reservoir 13.  The compositions of each reservoir are then pumped to mixer 16, the discharge rate of the catalyst mixture being 3.8% of that of the pre-polymer composition.  The mixer is supported on a traversing device, which may comprise rollers 18 on tracks 19. The liquid foaming mixture is spread via tube 20 on to carrier web 21, e.g. of woven fabric or metal sheet, which may be coated with a release agent (e.g. silicone rubber, wax, polyethylene, or polytetrafluoroethylene).  The carrier web may be an endless sheet as shown, or alternatively it may be a sheet which is unwound from one roll on to another.  The thickness of the foaming mixture is determined by the gap between doctoring rolls 28, 29 which are preferably coated with layers of rubber 30, 31. As the foaming mixture on carrier web 21 is drawn between rolls 28, 29, it is covered by a covering web 35, which may be an endless belt as shown, or alternatively a sheet which is wound from one roll on to another, and which may be coated with a release agent.  The foaming mixture is expanded between the carrier and covering web surfaces as the webs pass through heating zones 41 and 42.  The zones may be heated by steam to 125 DEG  F.  After emerging from said zones in a partially cured condition, the foam sheet is chilled by a cooling roll 49, which has a suitable refrigerant therein, to a temperature of for example 25 DEG  F., thus solidifying the polymer. Both webs may then be removed from the foam sheet (not shown). The foam product is of uniform density.

Title: Process of and apparatus for producing pantaerythritol
IPC: C07C29/38
Filed: 1961-02-13
Abstract: Pentaerythritol is continuously produced from formaldehyde and acetaldehyde in the presence of a strong alkali by introducing the acetaldehyde into the reaction zone in portions such that while the overall mol ratio of formaldehyde to acetaldehyde in the reaction zone is from 4.5 to 6 the local ratio in some parts of the zone is much higher.  The acetaldehyde may be fed separately into several reactors connected in series or into several zones of a single reactor.  The pentaerythritol solution produced is preferably subjected to a multi-stage concentration, the first stage being under high vacuum and the last being under at least atmospheric pressure. The solution leaving the last stage may be subjected to countercurrent stripping either by the steam used for heating or by the vapours obtained from the last step. Pentaerythritol is obtained by crystallisation from the final solution.

Title: Improvements in or relating to signs, name-plates and the like
Filed: 1959-02-16
Abstract: 947,381. Moulding signs, name-plates &c. J. T. JENKINS. Feb. 16, 1960 [Feb. 16, 1959], No. 5355/59. Heading B5A. A sign, name-plate or like article consisting of characters carried by a base plate is made by inserting moulding material for the characters into recesses within a base plate mould, setting or part-setting the moulding material within the recesses, adding to the mould further moulding material for the base plate and setting the base material so that it bonds with the character material. The moulding material may be a coldsetting, thermo-setting or thermoplastic resin. For cold or thermosetting resins, the character material is not completely cured during the moulding of the characters, complete curing being effected at the same time as the curing of the base material, during the final stage of the process. When a thermoplastic resin is used, the face of the character material adjacent the base material is softened sufficiently to produce a bond. If the characters are to stand in relief from the base plate, a mould is used in which recesses in the bottom surface form the characters, but when the characters are to be flush with the base plate, a stencil cut to the required form of the characters is inserted into the mould, being removed before the base material is applied. The character material and/or the base material may be reinforced if desired, e.g. with glass fibre.
